CAR-WHEEL AND AXLE.

SPECIFICATION forming part of Letters Patent No. 770,583, dated September 20, 1904.

Application filed October 9, 1903.

T0 all. whom tmay concern:

Be it knownthat I, WILLIAMARTHUR HONEY- MAN, a citizen of the United States, and a resident of Wallace, in the county of Shoshone and State of Idaho, have invented a new and Im-- proved Oar-Wheel and Axle, of which the following is a full, clear, and exact description.

This invention relates to certain novely and useful improvements in portions of the trucks used in railway rolling-stock, and has particularly application to a new form of axle, axle-boxing, and wheel designed for use in connection with mining-cars.

In carrying out the present invention I have particularly in view as an ob ject the provision of an improvement which will be exceedingly simple in its construction and one which will be durable-that is to say,'able to stand the hard uses incident to the condi tions under which it is employed.

It is also my object to provide an axle which is self-oiling and to arrange and correlate the parts of the entire structure so that it will be cheaper, lighter, and simpler in having a less number of parts than are ordinarily found in use on mining-cars.

Another object of my invention is to provide an improved means for locking the wheels in position on the axle, the construction being such that a minimum of friction is had With the maximum strength and security.

With the above-recited objects and others of a similar nature in view the invention consists in the construction, combination, and arrangement of parts, as is described in this specification, delineated in the accompanying drawings, and set forth in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

taken on the line 5 5 of Fig. 1, showing in Serial No. 176,391. (No model.)

detail thev locking-gib of the wheel on the axle; and Fig. 6 is a sectional view on the line 6 6 of Fig. 1.

Referring now to the accompanying drawings in detail, 5 designates an axle which is preferably in the nature of a cold-rolled steel shaft, having a groove 6 lformed at each end thereof, one end portion of the 4axle being flattened, as at 7, to [it a flat face or shoulder 8, cored in one of the hub portions 9 of the wheels 10. The hub portions 9 are adapted to be slipped over the ends of the axle,l as shown in Fig. 1, and the iiattened face 7 at one end of the axle coincides with the cored shoulder 8 in one of the hubs, making a perfect fit and causing the axle to revolve with one wheel, While the other wheel runs independently, thereby reducing friction when the car is turning curves. Each of the wheels 10 is formed in one solid casting, and the web portions 11 of said wheels, which radiate from the hub, are curved or irregular to counteract any shrinking which results in cooling the wheel after it has been cast. The outer or cap portion of each hub is formed with a vertical straight bore 12, designed to permit the passage of the shank portion 13 of the locking-gib 14, the head portion 15 of said gib or key having an approximately semicircular recess 16 cut therein, which recess is designed to seat in the reduced portion formed by the groove 6 at the end of the axle, the Lipper' part of the hub of the locking gib or key being preferably widened by means of flanges 17, so that said anges rest upon the outer surface or periphery of the hub. A lockingnut 18 is screwed upon the threaded end portion 19 of the shank of the gib to retain the same in its operative locking position. As will be seen by reference to the drawings, there is one gib or key for each Wheel, and it will further be noted, by reference to Fig. 5 in particular, that the extension 2O of the head portion of the gib opposite the shank thereof tapers downwardly and is adapted to fit within a groove 21, cut in the interior face of the hub. If desired, this extended portion 2O may be in the form of an additional shank-that is to say, a counterpart of the shank 13--and may be secured in a similar manner.

The purpose of having the boxing cover the ends of the hub is to provide a tight joint` which will prevent dirt, dust, or the like from sifting in upon the axle and also to prevent the escape of the lubricating-oil when the latter has been placed in the boxing. lThis boxing is preferably formed of an upper section 26 'and a lower section 27, said sections having projecting apertured lugs 28, the apertures in said lugs permitting the passage of bolts or screws for securing the boxing in place. An aperture 8() is formed in the upper section to provide for the admission of a lubricant to the boxing, and said upper section is also provided with slots or openings 3l to allow the oildistributing rings32, carried by the axle 5, to turn therewith without hindrance and also to permit the insertion of these rings. If desired, a cover 32 may be provided for the lubricating supply-opening, said cover being in the nature of a slide which may be moved from side :to side to close the opening 30. 'Ihe boxing is also preferably provided. with a plurality of strengthening-ribs, as will be clearly seen in Figs. l and 4.

The many advantages incident to my improved wheel and axle will be readilyapparent. It will be noted that the axle is self-oiling and is thoroughly protected from the admission of dust, dirt, or the like to the portions of the axle upon which the wheels are mounted.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- l. The combination of an axle having an annular groove formed adjacent to each end thereof, one of the end portions of the axle being flattened, and wheels adapted to fit over the ends of the axle, the hub of one of said wheels having a shoulder formed therein, adapted to seat the flattened end portion of of said wheels having a bore extending entirely through the hub portion thereof, and a locking-key having a shank adapted to pass through the bore in each hub, the head of the key engaging with the adjacent grooved end portion of the axle, substantially as set forth.

3. The combination of an axle having an annular groove formed at each end thereof, wheels having hubs cast integral therewith, designed to fit over the ends of the axle, each of said wheels having a vertical bore extending through the hub portion thereof, and a locking-key for each wheel portion, said key being formed with an enlarged head portion and a shank portion, the shank passing through the bored portion of the hub, while the head portion is designed to engage with the groove in the adjacent end of the axle, substantially as set forth.

4. The combination of an axle provided with an annular groove encircling the same, a wheel provided with a substantially cylindrical hub encircling said axle at a point adjacent to said annular groove, said hub being provided with a keyway extending through the same, and a locking-key disposed withinV said keyway and provided with a portion extending into said annular groove.

5. The combination of an axle provided with an annular groove encircling the same, a wheel provided with a substantially cylindrical hub encircling said axle at a point adjacent to said annular groove, saidhub being provided with a keyway having a comparatively large portion and a comparatively small portion, said keyway extending entirely through said hub, and a locking-key provided with a head disposed within said large portion and with a stem disposed within said small portion, said key extending entirely through said hub and loosely engaging said annular groove of said axle.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.

lWILLIAM ARTHUR HONEYMAN.
